I humbly suggest taking a peek at my thread in the Player Guides and Strategies section on Ancient Wonders. There actually are more AWs for non-fighting purposes, but it might be that you haven't unlocked to that point yet.
Thank you. That is exactly what I need. I'm only on chapter 11, so I haven't got most of them yet but it will be useful to know what to reject when I reach them. In the meantime I will have a good idea what to upgrade when I can.
